[Spce-user] Feature codes

[Joan Cifre (ibred)]

Hello,
we are trying the feature code *31*number to hide the identification 
number for the follower and it does not work, the call is hangued after 
the last *, any ideas that how can be happening?
Thanks!
Joan

By default, the following codes are configured for setting features.
The examples below assume that there is a domain rewrite rule
normalizing the number format 0<ac><sn> to <cc><ac><sn> using 43 as
country code.

72 - enable Call Forward Unconditional e.g. to 431000 by dialing
*72*01000, and disable it by dialing #72.
90 - enable Call Forward on Busy e.g. to 431000 by dialing *90*01000,
and disable it by dialing #90.
92 - enable Call Forward on Timeout e.g. after 30 seconds of ringing
to 431000 by dialing *92*30*01000, and disable it by dialing #92.
93 - enable Call Forward on Not Available e.g. to 431000 by dialing
*93*01000, and disable it by dialing #93.
50 - set Speed Dial Slot, e.g. set slot 1 to 431000 by dialing
*50*101000, which then can be used by dialing *1.
55 - set One-Shot Reminder Call e.g. to 08:30 by dialing *55*0830.
31 - set Calling Line Identification Restriction for one call, e.g.
to call 431000 anonymously dial *31*01000.
80 - call using Call Block Override PIN, number should be prefixed
with a block override PIN configured in admin panel to disable the
outgoing user/admin block list and NCOS level for a call. For example,
when override PIN is set to 7890, dial *80*789001000 to call 431000
bypassing block lists.
You can change any of the codes (but not the format) in
/etc/ngcp-config/config.yml
